3 Claims. (Cl. 220-60) This invention relates to improvement incontainers and more particularly to the provision of a container ofnovel features useful for dispensing of pharmaceutical and medicinalpreparations, and other products, the container having a body portionopen at the upper end and a positive snap-action closure cap therefor.The body portion and closure cap have complementarily formed registeringparts so proportioned that the closure cap may be positioned on theupper end of the body portion and then snapped into therewith, thereuponhaving interfitting contact therewith.

These and other advantageous objects, which will appear from thedrawings and from the description hereinafter, are accomplished by thestructure of my invention, of which an embodiment is illustrated in thedrawings. It will be apparent, from a consideration of said drawings andthe following description, that the invention may be embodied in otherforms suggested thereby, and such other forms as come within the scopeof the appended claims are to be considered within the scope and purviewof the instant invention.

In the drawings:

Fig. 1 is an elevational view of a container embodying the invention,

Fig. 2 is an enlarged, transverse, partly sectional, partly elevationalview thereof, taken on line 2--2 of Fig. 1,

Fig. 3 is a further enlarged fragmentary sectional view taken on line3-3 of Fig. 2, showing the closure cap, initially positioned on the bodymember prior to assembly thereon, and

Fig. 4 is a similar view, showing the position of the closure cap on thebody member at the completion of the closing operation.

As shown in the drawings, the container of this invention comprises abody portion open at its upper end 11 (Fig. 3) and having a rib 12formed on the outer wall of the body portion and defining, with theupper edge 13 thereof, a shouldered recessed portion 14. The bodyportion 10 further has a recessed portion 15 in its outer wall beneaththe rib 12. A closure cap is provided pursuant to the present inventionfor cooperation with the rib 12 of the body portion to close the upperend of the body portion. Said cap comprises a cap closure portion 21 anda depending flange 22, preferably of more flexible material than the ribportion of the body portion. An internal rib 23 is formed on the flange22 and the parts are preferably so proportioned that when the cap ispositioned on the body portion (Fig. 3) the internal rib of the flangedportion of the cap first contacts the rib 12 of the body portion andflexes outwardly (arrow A,

Patented Jan. 22, 1957 ICE Fig. 3). The rib 23 of the cap rides alongthe outer face of the rib 12 and then flexes (Fig. 4) inwardlly in thedirection of the arrow B of Fig. 4, and into registering engagement withthe lower end 24 of the body portioned rib 12. The internal bead 23 ofthe flange 22 of the cap is preferably pointed inwardly, terminating inthe point 25 directed inwardly of the cap. The cap also has an internalhead 26 at the juncture of the top and flanged portions thereof ofcomplementary outlline to the shouldered recess 14 intermediate theupper edge and rib of the body portion, adapted to snap into said recess14 when the cap is assembled on the body portion (Fig. 4) with apronounced snap, or click, to provide a double registration of the capat the upper and lower ends of the body portion rib. Thus, the parts arefirmly interlatched and the top of the body portion 10 of the containereifectively closed until such time as it may be desired to open same,whereupon the cap may be readily lifted from the body portion.

The cap may be provided with an external rib 27 in registry with theinternal rib 23 of the flanged portions of the cap, to provide furtherstability to the device in the engaging and disengaging operations abovereferred to.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A container comprising a body portion open at its upper end, a ribformed on the outer wall of the body portion and projecting therefromadjacent the upper edge of the body portion and defining, with the upperedge thereof, a shouldered recess, said body having a recessed portionat its outer wall beneath the rib, a closure cap for cooperation withthe rib of said body portion to close the upper end of the body portion,said cap comprising a top closure portion and a depending flange of moreflexi ble material than the rib portion of the body portion, an internalrib formed on the flange of the cap, the parts being so proportionedthat when the cap is positioned on the body portion, the internal rib ofthe flanged portion of the cap will first contact the rib of the bodyportion and flex outwardly, riding along the outer face thereof and willthen snap inwardly and into registering engagement with the lower end ofthe rib securing the cap on the body portion, said cap having aninternal head at the juncture of the top and flange portions thereof ofcomplementary outline to the shouldered recess intermediate the upperedge and rib adapted for registration with and to snap into the recesswhen the cap is assembled on the body portion, to provide a doubleregistration of the cap at the upper and lower ends of the body portionrib.

2. In a container as set forth in claim 1, said internal rib of the capbeing of pointed cross-section, with the point thereof directedinwardly.

3. In a container as set forth in claim 1, said cap having an externalrib portion in registry with the internal rib of the flanged portion ofthe cap.
